Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
This mattress makes sense if you want memory foam comfort without the fully sunk-in feel that all-foam models can give. The 1400 Mirapocket springs respond independently to movement, which means less disturbance from a restless partner and better spinal alignment than a basic open-coil design. The firm rating suits back and front sleepers, and heavier bodies that need extra pushback. From £349 it sits at an accessible price for a pocket-sprung hybrid, and the 60-night trial gives you a proper chance to test it at home. Silentnight is a long-established UK name, and the 5-year guarantee covers manufacturing faults for a reasonable stretch, though some rivals do offer longer.
Key Features & what's inside
- Memory Foam. A memory foam layer that moulds to your body, which means pressure is eased from muscles and joints as you settle in. Expect a gentle cradle rather than a deep sink, given the firm overall feel.
- Mirapocket Springs. 1400 Mirapocket springs sit beneath the foam, each responding independently to your movement. In practice that means targeted support along your spine and less motion transfer across the bed.

Who's it NOT for?
If you sleep on your side and weigh less, a firm mattress like this may not let your shoulder and hip sink in enough, which can cause pressure points. It's also not ideal if you love a plush, enveloping feel, as the memory foam layer sits over a firm sprung base.

How firm is the Silentnight Memory 1400 Pocket mattress?
Silentnight rates it as firm. That suits back and front sleepers who want plenty of support, though the memory foam top layer softens the surface slightly. Lightweight side sleepers may find it a touch too firm for comfortable pressure relief at the shoulder.
Does the Silentnight Memory 1400 come with a trial period?
Yes. Silentnight offers a 60-night trial, so you can sleep on it at home and return it if it doesn't suit. It also comes with a 5-year guarantee covering manufacturing faults.
How deep is the Silentnight Memory 1400 Pocket mattress?
It's 25cm deep, which is a fairly standard depth for a hybrid. Most regular fitted sheets should fit without any trouble.
What sizes does the Silentnight Memory 1400 come in?
Five UK sizes: single, small double, double, king and super king. Prices range from £349 to £726 depending on the size you choose.
How long does delivery take for the Silentnight Memory 1400?
Silentnight lists delivery within 14 days. That's slower than some brands manage, but it gives you time to arrange disposal of your old mattress.
